hi, i have a question about the behavior of funktions.
if theres a function:
f(A,0) ->
1;
f(A,B) ->
[f(A,B-1),f(A,B-1)].
how often is f(A,B-1) evaluated then ? just one time, and erlang tooks
the result everywhere where it fits, like f(A,B) -> TMP=f(A,B-1),[TMP;TMP].
or is it evaluated every time again ??
greatz Johannes
